Recent research
Scientists are refining their taxonomic strategies in the hope of developing a standardized method of classifying, identifying, and describing the evolutionary history of species. The following links will take you to original research addressing these issues.
- DNA Barcodes and Bird Identification, PLoS Biology
- DNA Barcodes and New Butterfly Species, PNAS
- New Zealand's Extinct Giant Eagle, PLoS Biology
- New Tiger Subspecies, PLoS Biology
- Conservation of Asian Elephants, PLoS Biology
How do scientists identify and name species?
What is a species? Scientists don't agree on the exact definition of a species. Read about species concepts on this UC Berkeley site.
What is taxonomy? Taxonomists name and classify living things, so they play an important role in determining how we define species. Read more about taxonomy at this Vision Learning website.
Who was Linnaeus? Read about the taxonomist Linnaeus on this UC Berkeley site.
What are the current approaches to classification? Scientists today use morhological (physical) traits, embryology (patterns of development), and molecular biology to identify species.
